Has user Profile Edit disappeared during recent upgrade or do I have wrong browser/version/capabilities/expectations? However, I managed to edit mine by specifying http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?action=profile;username=nnn

What should we see between two bars up there in banner, between "Members" and "Logout"?

you are talking about changing your profile in the old forum right? That one is disconnected from the new one. The new forum profile shows up in the Menu Bar. Any changes you make at the old forum will not work, nor be shown in the new one. From the moment we migrated the forum, we disconnected it from the Arduino system.
